The direct answer to your question is no.
The autocorrect "learns" as you correct it for correcting you. After some time of use, it will start auto correcting your words to words you've used previously. Itll probably be a PITA, but you could get it to "learn" all of the words you use in any language. Just keep going back and retyping those words, and if you use it frequently, it shouldnt be too long before it learns your vernacular and actually helps you write in Tagalog.
